-5- Surface Water 7. No sample of water quality in the pond was contained in Exhibit 11 as stated on page 2.04-18. 8. The data collected for surface water quality is not adequate to define the water quality of Coal Gulch. At a minimum, samples should be presented for water quality upstream and downstream of the proposed mining operations over a consecutive twelve month period. These samples should be collected on Coal Gulch itself, not on adjacent streams. 9. No information was presented to identify seasonal variations in water quality or quantity of Coal Gulch. A monitoring program for future potential impacts should also be developed. ]0. Section 4.05.2 states that the pH of the pond was reported as being less than 6.0 in Section 2.04.7 of the permit application. No such information was found in this section. 11. The Division does not feel that there is any evidence to support the applicant's reasoning in discussing the development of the low pN water present in the pond. Furthermore, the Division feels that there is significant potential for subsurface water to be causing the low pH. The applicant should revise this and other appropriate sections of the permit application to include a discussion of actual evidence to support the statements made. Alternative Water Supply 12. The requirements of this section of the regulations have not been addressed. The conclusions drawn in this section of the permit can not be substantiated. More information is required before the applicant can be released from demonstrating that an alternative water supply is available or necessary. 13. No map was submitted showing water supply intakes, irrigation ditches, reservoirs and wells within a one mile minimum radius of the affected area. No current users of surface water were identified. Monitoring 14. Section 4.05.13 needs to be revised to reflect a surface and ground water monitoring program for the life of mining. Climatological Information - Rule 2.04.8 1. The applicant should provide monthly averages for both temperature and precipitation in Tables 4 and 3 respectively. The applicant should also provide temperature range data and average velocity of prevailing winds information.
